Channels Section

The Channels Section of the 9250 application only affects the 9250’s channel parameters.

Complex pulse trains can be created by combining various system and channel modes. As

shown below in Figure 6.3, the following channel parameters may be altered:

Figure 6.3 –9250 Application: Channel Parameters

 Channel Selection: Select the proper Channel tab in order to further edit the

parameters on the corresponding channel.

 Enabled: Enables and Disables the output for the selected channel.

 Delay: Sets the delay from the timing reference to when the pulse is created. Valid

input is ±4000s with 5ps increments. Note: negative delays are only applicable if you are

referenced to a channel that has a positive delay.

 Width: Sets the pulse width for the selected channel. Valid input is 8ns – 4000s with

4ns increments.

 Amplitude: Allows the user to select the voltage amplitude of the output. Valid values

are 3.3V – 5V with 20mV increments.

 Channel Mode: Changes the Channel Mode to Normal, Single Shot, Burst, or Duty

Cycle.

o Normal: Channel will produce pulses as long as a T

is present (mimics System

Pulse Mode)

o Duty Cycle: If Duty Cycle has been selected in the Channels section, the unit will

generate a continuous pulse stream in which outputs will be On for “N” pulses

and Off for “M” pulses. One may alters the “N” (On) and “M” (Off) parameters:

 On Counts (“N”): Positive integer value which designates the number of

pulses to produce during the “On Cycle.” Valid inputs are 1-1,000,000.

 Off Counts (“M”): Positive integer value which designates the number of

pulses to suppress during the “Off Cycle.” Valid inputs are 1-1,000,000.
